Hi,
Situation.
I’m at sea and my chart shows a target some miles away.
I navigate in the direction of the target.
When I am within a range of 2 miles I dive to 30 meters, stop engines and check the hydrophone.
No sound?
I surface back to periscope depth and check the outside for the contact.
Nothing?
I move the sub so that is showing directly under the target on the chart.
I do all of the checks mentioned above.
Still Nothing?
I surface and check with the binoculars.
Nothing to be seen?
Some times the target slowly fades away when I get closer.
This is not the case with all targets.
Please help.
